hello all, I just noticed I have some weird vibration noise at 110km\h and only at that speed. The car doesn't vibrate itself but I can hear some kinda of vibration\rumble, but u have to listen to hear it, like turn the stereo off. Thanks for any advice!

Is this vibration real low frequency, and fading in at about 68 mph and out by 72 mph? I have owned two manual trans GT 2006 mustangs and both have the problem, and the first one got a new driveshaft in an attempt to rid the car of this after a rearend rebuild, and when that didn't totally fix it, an entire rearend assembly from the assembly line to replace the housing and guts complete. Still there, so that is why i bought the second one, to get rid of the vibration.(and to get a different color and wheels!)

So they never figured out the problem then? This only just started yesterday and I have owned the car for 2 1\2 months now. But it pretty much does as you described.

there are a number of TSBs (technical service bulletins) on this car because the exhaust tends to vibrate off the transmission crossmember at certain RPM.....usually 3,200 RPM. Also the heat shields tend to vibrate.

Don't know if this helps you or not but it's something to consider.

Check into TSB 06-04-1--V8's exhibit vibration at 1200 and 3200 rpms due to the exhaust. The noise will come out of the console where the gearshift is or where the heater controls are located, per the TSB. The fix is easy-- 2 #40 stainless steel clamps to clamp down the exhaust hanger isolaters being loose.

110km/hr ~ 70mph so what gear are you in when you hear this--4th perhaps? If so that should put you close to the 3200 rpms above.

Hope this helps.
